Software Updater does not automatically install updates not signed by
trusted authority

Symptoms

Software Updater does not automatically install updates not signed by trusted authority.

Diagnosis

Some updates, for example Notepad++, WinZip, and 7-Zip, are released unsigned. Software Updater does not automatically install unsigned updates and issues the following installation error:

There is no signature.

Solution

The administrator can use the selective installation from the Policy Manager Console to install these updates.

Alternatively, the administrator can use the setting 1.3.6.1.4.1.2213.59.1.20.30 to 'Allow unsigned updates automatic installation'. Note, however, that this may decrease the level of protection, because it applies to all future updates, which are installed according to automatic installation rules, including missing updates of newly installed products.
